Summary
The objective of this study was to compare the transversal symmetry of the upper maxilla starting from the canine towards the anterior contrasting the cleft side and the non-cleft side with respect to the centerline. A retrospective and comparative study of the quantitative type. Sixty study models of children were analyzed with mixed dentition with unilateral cleft lip and operated velum cleft, these patients were from the Craniofacial Malformation Unit and the Luis Calvo Mackenna Hospital. The anterior transversal length of the maxilla wasdetermined at the canine level, then the anterior length of the maxilla at the level of the center line was determined, which was split into thirds. The transversal length of each side was determined from these points to the center point of the alveolar ridge. There is a significant stastistical difference between the transversal length of the cleft and non cleft side with regards to the center line, with the latter being greater on all three measuring levels. No difference was shown regarding sex (P>0.05). On patients with unilateral cleft lip and operated cleft palate, the anterior zone of the upper maxilla shows an asymmetry in the transversal direction. The difference is greater at the canine level and tends to flatten out on the cleft side. A longitudinal study is suggested that this would show an evolution of such asymmetry in a time period.
KEY WORDS: cleft lip and palate, transversal symmetry, congenital abnormalities.
